supplying water to the water jacket. a citizen of the United Referringfirst to the general arrange- Pittsburgh, :in the county of Alleghenyand ment of parts indicated in Fig. 1, 1 is the State of Pennsylvania,have invented cerwater jacket around the cylinder of the gas tain newand useful Improvcmcntsin Valves engine illustrated; 2 is the watersupply for \Vater-Jacketcd Explosion-Engines, of pipe for the jacket,connected to a water which the -t'ollowing is a specification. main; 3is the drain pipe for the water The invention relates to explosionengines, jacket, such drain pipe leading into the and particularly tovalve mechanism for sewer a 5 is the gas or fuel supply pipe controllingthe inflow and drainage of the leading to the carhuretcr (i; 7 is thewater water jacket. The invention has for its outlet pipe from thejacket, leading to the primary objects; the provision of an iinsewer;and 8 is the casing of the valve mechproved sai'cty arrangement ofvalves for anism for controlling the supply of fluid insuring theopening of the drainage outlet through the pipes 52, 3, and from thewater jacket and closing of the The construction of the valvemechanisminlet thereto when the fuel silpply inlet is in the casing 8 will heunderstood by referclosed, and vice versa; and the provision of once toFigs. 2, 3, and t, Mounted in the means oi the character specified ofvery casing are three transversely extending rocompact construction, andone in which improved means are Tu'ovided for throttlingthe fluidspassing through the inlet pipes.

illustrated in the aecoi'npairying drawing, wherein- Figure 1 is a sideelevation of an engine valve applied thereto, is a transverse sectionthrough the tary valves 9, l0, and 11 (Fig. 3). These valves are taperedin the customary way in order to make a tight tit, and are provided withthe transverse openings 12, 13, and 14 adapted to register with theopenings 15, 7 10, and 17 extending through the valve easire, it beingunderstood that theportions of the pipes Q, 3, and 5 lying on oppositcsides of the valve casing, S are screw valve mechanism, on the lineII--II of Fig. threaded into the sockets on opposite sides 3, Fig. 3 isa plan view of the alve, with of the casing as indicated in Fig. 52, sothat one of the three similar parts thcrcol" in the passages 15, Hi, and17 constitute in section to show the interior construction, cil'cctportions oi the pipes 5, 3, and 2, re and Fig. 41- is a side elevationof the valve. spcctively.

It :lrequently happens in cold weather The outer ends of the valves 9,l0, and that the water jackets of gas engines are 11. are squared asindicated in [*ig. 4-, and burst through failure to drain the jacketcarry the ha dles 18, 1S), and 20 connected after the engine has stoppedat night, and by the bar 21. The handle 19 is extended as failure to cutoil the supply of water to the indicated at 22, to provide an operatingjacket. My invention is designed to overmeans so that the three valvesmay he moved coinethis diiiiculty, by the provision-of ansimultaneously. When the member 22 is arrangement whereby the drainagepipe in the position indicated in Figs. 1 and 4-, from the water jacketis opened and the the valves occupy the position indicated in supplypipe closed, when the gas supply is Fig. 2, at which time the drain pipe3 is cut oft. Conversely the arrangement proclosed and the gas and waterinlet pipes vides for the closure of the drainage pipe are open, thisbeing the position when the and the opening of the supply pipe to theengine is working. It will-he seen that the jacket, when the gas or fuelsupply pipe is member 22 must he moved to this position opened. Thearrangement not only guards in order to admit fuel to the engine, andagainst the bursting of the Water jacket that this movement insures theopening of through failure to drain the jacket after theengine isstopped the water inlet pipe at night, but also to the jacket, and theclosing of the drain,

so that all danger of mediately drain,

running the engine with an empty jacket is eliminated. When the handle22 is swung 90 to the right the drainage valve 10 is opened, and the gasand water inlet pipes.

5 and 2 respectively closed, such movement occurring when the engine isshut down. The closing off of the gas therefore necessarily involves theopening of the drain pipe and the closing of the water supply pipe tothe jacket, so that the jacket will imand all danger of bursting due tofreezing with a full jacket is avoided.

The inner ends of the valves 9, l0, and 11 are threaded as indicated at23, such threaded portions carrying the washers 24 and nuts 25. One sideof the threaded portion 23 is cut away to provide a Hat surface 26, andthe interior of the washer 24. is formed 4 so as to fit the fiat portion26 so that-the washer turns with the valve. This eliminates the tendencyof the nut to unscrew as would be the case if the washer did not turnwith the valve. This is a well known mechanical expedient "for which noclaim is made.

Inside each of the valves 9, 10, and 11 is a rotary throttling plug.These plugs are all similar in construction and bear the referencenumerals 27, 28, and 29 (Figs. 2 and 3). as indicated in Fig. 3, thecentral portion of the plug 27 is-partially cut away so that theplug'only partially blocks the passage 12. It will be seen that more andmore of the passage 12 may be blocked by the plug 27, by rotating itabout its axis. This plug therefore serves as a convenient means forthrottling the flow of fluid through the valve casing. The outer ends ofthe plugs 27, 28, and 29 are squared and carry the relatively shorthandles 30, 31 and 32 SFig. 4). The flow of fluid through each of t 1evalve parts may thus be readily throttled to suit conditions, and thenecessity of other throttling devices in the pipes 2, 3, and 5 is thuseliminated. N

The inner ends of the throttling plugs 27-, 28, and 29 are provided withscrew threaded portions 33 carrying washers 34 and nuts 35. The portions33 have a flat portion at one side so that the washers 34. which fit theflat portions turn with the stems 33 and nuts 35, and any tendency tounscrew 'the nuts is eliminated. The plugs 27, 28, and 29 are tapered inorder to make a tight fit with the valves through which they extend.

It will be understood that the particular embodiment of the inventionillustrated and described constitutes only one of a number of forms inwhich "the invention may be practised. The invention is readilyapplicable to systems other than the one shown for providing acirculation of water through the water jacket, the system illustratedbeing somewhat wasteful because the water is directed back into thesewer instead of bebut such system is sufficient for the purposes ofillustration.

variety of valve structures might be substituted for the one shown, theonly requr we ment being that the common operating means control allthree passages, so that when the drain is closed the gas and Watersupply pipes will be open, alidwice versa. The use of the threeindependent valves is not necessary, although convenient in that itpermits independent, adjustment and independent accessibility'to eachvalve for the purpose of repairs. lit is also obvious that wheresepanate valves are used as illustrated, a large number of dificrentmechani cal equivalents might be employed for se curing simultaneousmovement of the valves, depending upon the character of the valves andtheir degree of proximity.

What I claim is:
